Specification of Letters Patent.

provide, in a structure of the sort above referred to, a nozzle which islongitudinally adjustable in a line substantially at rlght angles to thedirection of movementrofthe' dilating mechanism. I

A further objectis to provide novel means" for mounting the nozzleforlongitudinal sliding movement, and to provide novel means for limitingthe movement of the nozzle. I

The invention further aims'to provide a novel means for connecting thecovering with thecas1ng,-and for'connecting'the cas- If ing with thebridge in which, the nozzleis slidably mounted.

With the foregoing and other objects in view, which will appear. as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changesin the preciseembodiment of invention herein disclosed can be made within the scope ofWhat is claimed without departing from the spiritof the invention.

outer end of the tubular nozzle 11 is threaded as shown at 12 to receivethe collar 14 Patented Dec.'24, 1912. Application filed February 15,1912. 7 Serial No. 677,672.

of a tip 1 5,having discharge slits 16 ex 2 tended intherdirection of,the length of the i nozzle 11. The opposite endof the tubulardischarge'nozzle 11 is threaded as shown at 17 to'receive a sleeve18,.having a'series of I tapered shoulders 19, adapted to receive andt-ohold a supply tube; I

InFig. 7 there is shown'in detail, an actuating. disk 20 having acentral opening 21, surrounded by. an upstandingflange 22.

The arms 6 of the bridge 1 extend through the opening21, the .disk20rotating upon the flange 2 of the bridge 1, and the flange 22constituting a means whereby the actuating disk is journaled forrotation onthe i arms 6 of thebridge 1.; In the'upper face I e of theactuating disk 20 there is a series ot cam slots23.

In Fig. 4, a tubular casing24 shown.

The casing 24 incloses the arms 6 of the bridge 1, and is provided inits side wall with openings 25, adapted to be alined with the openings 7in the arms6 of the bridge 1. The side wall of the tubular casing 24 isequipped with longitudinally extended ribs 26, between which the arms 6of the bridge 1. are adapted to flt, thereby to aline the openings 25and 7 in the tubular casing 24 and 1n the arms 6 of the'bridge,respectively;

Projecting from the lower end of the tubular, 3 v

casing 24 is a flange'27,'preferably square in peripheral-outline.Projecting from the upper end of thetubulartiasing 24 is an upper flange29,'pre,ferably of circularperipheral outline. In the flange 27 thereare slots30,

and in the flange 29 there are slots 31, the slots31 and30 being alined.I

35, the long arm 34 being equipped adjacent its free end,,with laterallyprojecting fingers 36. Upon the free end of the long arm 34 there isa'shoulder 37 which extends toward the short arm 35. Project-ingoutwardly fromthe long arm 34 is a-boss 38, and projecting outwardlyfrom the short arm 35 is a knob 39.

The spring 32 is placed against the tubular casing 24, the bend 33 ofthe spring resting against the flange 27, and the fingers 36 extendingcircumterentially of the casing. The boss 38 registers in the alinedopenings 25 and 7 of the casing 24 and of the bridge 1, respectively, soas to hold the parts together.

About the springs 32 is placed a frusto conical cover 40, havingopenings 41 in its slanting side wall 42. The knobs 39 of the archedsprings 32 are adapted to register in the openings 41.

A dilating mechanism is provided, the same comprising a plurality ofarms 43, surrounding the nozzle 11 and located between the cover 40 andthe tubular casing 24. The arms 43 are fulcrumed in the notches 31 ofthe flange 29 of the casing 24, the arms being provided with enlargedheads 44, registering between the flanges 29 and 27, and preventing alongitudinal movement of the arms, without interfering with thetransverse movement of the arms upon the flange 29 as a fulcrum. Theenlarged heads 44 have reduced ends 45, adapted to move in the slots 30of the flange 27, the ends 45 terminating in reduced tips 46,registering in the cam slots 23 of the actuating disk 20.

The actuating disk 20 is journaled for rotation between the flange 27 ofthe casing 24 upon the one hand, and the flange 2 of the bridge 1 uponthe other hand. When the actuating disk 20 is rotated, the cam slots 23thereof will engage the tips 46 of the arms 43 and cause the free endsof the arms to be brought together, or to be expanded, depending uponthe direction of rotation of the actuating disk 20.

Owing to the fact that the cover 40, the tubular casing 24 and thebridge 1 are held against relative movement by the springs 32, theseelements may be separated readily, permitting the instrument to be takendown for cleaning, the knobs 39 of the springs 32 being removed readilyfrom the openings 41 in the cover 40, by pushing the knobs inward fromthe outside of the cover.

Obviously, the bosses 38, registering in the openings 25 and 7 of thecasing 24 and of the bridge 1, respectively, serve to hold these elements against relative movement. The shoulder 37 of each spring 32engages beneath the flange 29 ot the casing 24. Moreover, the bend 33 ofthe spring engages resiliently with the flange 27 of the casing 24,

the bosses 38 being thus maintained, prior to the application of thecover 40, in the alined openings 25 and 7.

The fingers 36 of the springs 32 extend beneath the arms 43, and whenthe arms 43 are swung inwardly at their lower ends, the fingers 36 exertan outward pressure against the arms, thereby preventing the arms fromrattling about, and from working too loosely.

Attention is directed to the fact that the nozzle 11 is longitudinallyslidable with respect to the arms 43, it being thereby possible toposition the tip 15 at any desired point along the distended vagina. Athorough cleansing of any part of the canal may be eflected by adjustingthe nozzle longitudinally, and since the nozzle is not onlylongitudinally slidable, but rotatable as well, in the bridge 1, thejets projecting from the slits 16 may be given a rotary motion withrespect to the distended or dilated surface of the canal. The nozzle 11is held in the bridge 1 against complete withdrawal, by means of the tip15 and the sleeve 18, either of which elements may be removed, therebypermitting the nozzle 11 to be withdrawn from the bridge 1.

The improvements herein disclosed and hereinafter claimed, permit theentire device to be taken down, without the use of tools, therebyrendering the structure thoroughly sanitary.

Having thus described the invention,what

is claimed is 1. In a device of the class described, a casing; a bridgein the casing; a nozzle carried by the bridge; dilating means fulcrumedupon the casing; a cover surrounding the dilating means; and an archedspring having oppositely extended projections upon its arms, one ofwhich projections is engaged with the casing and with the bridge, theother of which projections is engaged with the cover.

2. In a device of the class described, a casing; a bridge in the casing;a nozzle carried by the bridge; dilating means fulcrumed upon thecasing; a cover surrounding the dilating means; an arched spring locatedbetween the cover and the casing, the spring having oppositely extendedprojections upon its arms, one of which projections is engaged with thecasing and with the bridge, the other of which projections is engagedwith the cover, the spring being provided with a lateral finger extendedbetween the dilating means and the casing.

3. In a device of the class described, a casing; a bridge in the casing;a nozzle carried by the bridge; dilating means: fulcrumed upon thecasing; and an arched spring having one of its arms engaged with thecasing and with the bridge; and a cover for the dilating means, withwhich cover the other arm of the spring is engaged, the

i 7 cover being of tapered construction, to effect a compression of thelast mentioned arm of the spring, When the cover is movedlongitudinally.

.4. In a device of the class described, a tubular casing having guidesin its interior and provided with an opening; a bridge located betweenthe guides and having an opening alin-ed With the opening in the casing;a nozzle carried by the bridge; dilating means fulcrumed upon thecasing; a cover Witnesses Copies of this patent may be obtained for fivecents each, by addressing the Washington, D. G.

for the dilating means;=and a spring removably engaged with the coverand engaged with the alined openings. I

In testimony that I claim the foregoing as my own, I have heretoafiixedmy signature in the presence of two witnesses.
